How do you extract a string from a list in Python?

Example:

Input: ['Geeks', 'for', 'Geeks']
Output: Geeks for Geeks

Input: ['I', 'want', 4, 'apples', 'and', 18, 'bananas']
Output: I want 4 apples and 18 bananas

Let’s see various ways we can convert the list to string.

Method #1: Iterate through the list and keep adding the element for every index in some empty string.

Python3

def listToString(s):

str1 = ""

for ele in s:

str1 += ele

return str1

s = ['Geeks', 'for', 'Geeks']

print(listToString(s))

Method #2: Using .join() method

Python3

def listToString(s):

str1 = " "

return (str1.join(s))

s = ['Geeks', 'for', 'Geeks']

print(listToString(s))

But what if the list contains both string and integer as its element. In those cases, above code won’t work. We need to convert it to string while adding to string.

Method #3: Using list comprehension

Python3

s = ['I', 'want', 4, 'apples', 'and', 18, 'bananas']

listToStr = ' '.join([str(elem) for elem in s])

print(listToStr)

Output:

I want 4 apples and 18 bananas

Method #4: Using map() Use map() method for mapping str (for converting elements in list to string) with given iterator, the list.

Python3

s = ['I', 'want', 4, 'apples', 'and', 18, 'bananas']

listToStr = ' '.join(map(str, s))

print(listToStr)

Output:

I want 4 apples and 18 bananas

Method #5: Using enumerate function

Python3

s = ['I', 'want', 4, 'apples', 'and', 18, 'bananas']

listToStr = ' '.join([str(elem) for i,elem in enumerate(s)])

print(listToStr)

Output

I want 4 apples and 18 bananas

Method #6: Using in operator

Python3

s = ['Geeks', 'for', 'Geeks']

for i in s:

print(i,end=" ")

Use ''.join:

xs = ['1', '2', '3']
s = ''.join(xs)

If the list contains integers, convert the elements to string before joining them:

xs = [1, 2, 3]
s = ''.join(str(x) for x in xs)

How do you extract a string from a list in Python?

Calling str on each element e of the list l will turn the Unicode string into a raw string. Next, calling tuple on the result of the list comprehension will replace the square brackets with parentheses.
